Document Type and Number:
WIPO Patent Application WO/2024/009657
Kind Code:
A1
Abstract:
Provided is a motor control device comprising an estimation processing unit which includes an axis error estimation unit for using a voltage and a current applied to a motor and a rotation speed of the motor to estimate an axis error estimation value of an axis error of the motor and a calculation processing unit which includes a detection error correction unit for correcting a detected rotation angle of the motor on the basis of the axis error estimation value and calculates the rotation speed and the rotation angle of the motor on the basis of the detected rotation angle after the correction. The motor control device controls the motor on the basis of the rotation speed and the rotation angle of the motor.
